Innovative application of RTG in viaduct construction

RTG strategy in hoisting viaduct structural parts

Efficient lifting and precise positioning

In the hoisting of viaduct structural parts, RTG achieves efficient lifting and precise positioning with its powerful lifting capacity and precise control system. Traditional hoisting methods often require repeated adjustments between multiple hoisting points, which is inefficient and difficult to ensure accuracy. RTG, with its precise control system and powerful lifting mechanism, can complete the precise hoisting of structural parts at one time, greatly improving construction efficiency. At the same time, RTG’s tire walking device enables it to move flexibly at the viaduct construction site and adapt to various complex terrains, further improving construction efficiency.

Optimize construction process and improve overall efficiency

The application of RTG in the hoisting of viaduct structural parts is also reflected in the optimization of construction processes. By accurately calculating the weight, size and hoisting position of the structural parts, RTG can complete the hoisting of multiple structural parts at one time, reducing the number of hoisting times and hoisting time. At the same time, RTG’s control system can also monitor the hoisting process in real time to ensure the safety and stability of the hoisting process. This optimized construction process not only improves construction efficiency, but also reduces construction costs.

Safety and reliability of RTG in viaduct construction

Real-time monitoring and fault warning system

Safety is of vital importance in viaduct construction. RTG is equipped with an advanced real-time monitoring and fault warning system, which can monitor the working status of the lifting mechanism, electrical control system and tire walking device in real time. Once an abnormal situation is found, the system will immediately issue a warning signal to remind the operator to take timely measures. This real-time monitoring and fault warning system greatly improves the safety and reliability of RTG in viaduct construction.

Reduce construction accidents and ensure personnel safety

The application of RTG not only improves construction efficiency, but also significantly reduces the incidence of construction accidents. Traditional lifting methods often require operators to perform dangerous operations at high altitudes, which poses great safety hazards. RTG can achieve remote control operation through its precise control system and powerful lifting capacity, avoiding the risk of operators working at high altitudes. At the same time, the tire walking device of RTG also enables it to walk stably on complex terrain, reducing construction accidents caused by uneven terrain. This safe and reliable construction method provides a strong guarantee for viaduct construction.
